"For Le Bizec et al. (1999, 2002), although some ediblespecialties (e.g. wild boar testicles) are indeed rich innandrolone and could lead to an increase in nandrolonemetabolites in urines after consumption, only unusualquantities (100+ kg) would induce modification overthe IOC’s cut-off limit of 2 ng ml –1 urine."
I don't know if UKADs limits are the same as the IOC's.

"Indeed, nandrolone- or norsteroid-spiked food could lead to the excretion of increased 19-NA or 19-NE9 metabolites in the urine of concerned subjects. The same applies to such delicacies as wild boar testes. However, the quantities needed to be ingested to give a positive doping control would be enormous (Le Bizec et al.2002), since a portion of these substances is excreted directly in faeces (Dimick et al. 1961). Moreover, androgens and norsteroids have a bitter taste due to their chemical structure and large quantities of these substances should be detected by the consumer.
